GEORGE FOREMAN VS MOHAMMED ALI
The Rumble in the Jungle was a historic boxing event in Kinshasa, Zaire (now Democratic Republic of the Congo) on October 30, 1974 (at 4:00 am). Held at the 20th of May Stadium (now the Stade Tata Raphaël), it pitted the undefeated world heavyweight champion George Foreman against challenger Muhammad Ali, the former heavyweight champion; the attendance was 60,000. Ali won by knockout, putting Foreman down just before the end of the eighth round.
It has been called "arguably the greatest sporting event of the 20th century". It was a major upset victory, with Ali coming in as a 4–1 underdog against the unbeaten, heavy-hitting Foreman. The fight is famous for Ali's introduction of the rope-a-dope tactic.
The fight was watched by a record estimated television audience of 1 billion viewers worldwide, becoming the world's most-watched live television broadcast at the time. This included a record estimated 50 million viewers watching the fight pay-per-view on closed-circuit theatre TV. The fight grossed an estimated $100 million (inflation-adjusted $510 million) in worldwide revenue
